Large Hadron Collider Mysterious Object Detected In Tube

One concern De Roeck discussed is an "unidentified lying object" that could disrupt the accelerator's beam. Phys.org says physicists believe it's something to be "cautiously aware of." It hasn't caused a problem in the testing so far. "The unidentified lying object turns out not to be a problem for the operation, it's just something to keep an eye on," De Roeck said. "It's in the vacuum tube and it's not a problem if it doesn't move and remains stable." And if it moves?
